emacs and git...

Hi,

I guess it's a dumb...

I know that some of you work within emacs. I tried to use git iniside
a emacs shell (M-x shell) and had a weid behaviour:

$ git diff
WARNING: terminal is not fully functional
-  (press RETURN)

diff --git a/.lde/bin/cmd-version b/.lde/bin/cmd-version
index a6ce3f8..687112d 100755
--- a/.lde/bin/cmd-version
+++ b/.lde/bin/cmd-version

@@ -54,7 +54,7 @@ gdb_version () {

[snip]

I'm not using diff color option.

Can anybody shed some light ?

thanks
